CIMS环境下基于视图对象的多库集成与互操作技术

异构分布计算环境中多数据库的集成与互操作是ＣＩＭＳ环境下信息集成的一个主要研究领域。本文在分析这方面研究成果的基础上，结合ＣＩＭＳ环境下信息集成的需求，提出了一种基于视图对象（ＶｉｅｗＯｂｊｅｃｔ）机制的多库集成与互操作技术，其基本思想是通过视图对象的机制对多种数据源中的数据进行多层抽象与封装，以满足ＣＩＭＳ环境下不同层次的应用集成需求。文中还以公共对象请求代理结构（ＣＯＲＢＡ）为基础提出了基于对象请求代理（ＯＲＢ）的多数据库集成与互操作系统ＶＯ－ＭＤＢＳ的实现机制。

阶梯形CIM系统体系结构

实施ＣＩＭ的核心是系统集成,因此,成功的要诀之一就在于能否作好全局性的分析设计。ＣＩＭ系统体系结构就是为这种系统分析提供所必需的建模方法和工具。国际上已经提出了多种ＣＩＭ系统体系结构,它们各有长短,但其实用性都不够理想。本文作者于１９９３年在学习国外体系结构思想的同时,又结合中国国情,提出了一种六视图阶梯形ＣＩＭ系统体系结构。其中在ＣＩＭ系统体系结构中加入经济视图的观点,是作者于１９９３年在国际上首次提出的。

Development of a prototype customer-oriented virtual factory system

Current Computer integrated manufacturing/Enterprise Resource Planning (CIM/ERP) systems require harmony and communication between humans and facilities. A user’s preferences should also be considered in CIM/ERP systems. Virtual factory (VF), also known as virtual manufacturing (VM), systems can fulfill the requirements of current CIM/ERP systems. A VF system simulates virtual production in a virtual factory environment on the computer system which allows optimization prior to going into production. In this paper, we defined a VF system as a pre-analyzing system for designing, engineering and manufacturing a product in the enterprise system of the real world. The objective of this paper is to design a VF system and to develop a prototype system that the customer can participate in and be satisfied with. We selected a telephone as a sample product for the VF system. The VF system consists of four subsystems: virtual product ordering, design, manufacturing, and CIM/ERP interface. The prototype system aims to develop a virtual product ordering and design system.     

Evaluation of CIM technologies in Saudi industries using AHP

Successful implementation of computer integrated manufacturing (CIM) technologies offers manufacturing organizations numerous benefits (both tangible and intangible). The evaluation and selection process of these technologies is a very complex task due to the many parameters involved that should be taken into consideration during the selection process. In this research, a number of Saudi industries were surveyed to evaluate their current CIM technologies. Future plans regarding the implementation of such technologies are also investigated. This research also presents a decision support system (DSS) for the evolution and selection of CIM technologies, taking into consideration the requirements of manufacturing industries. This is done to ensure that the selected technologies comply with the objectives of these companies. Depending on the emerged results, a multi-attribute decision-making approach (analytical hierarchy process - AHP) is used. A computerized tool CIMAHP (selection of CIM technologies using AHP) is developed to simplify the application of the suggested DSS. Developed tools are tested and demonstrated using a real case study.

基于CIM的励磁系统建模

IEC 61970-301标准定义了能量管理系统(EMS)的应用程序接口(API).公共信息模型(CIM)是这个标准中的重要部分之一,它规定了这类API的语义.但CIM并没有对与同步机紧密相关的励磁系统建模.为了实现励磁系统与能量管理系统的标准化集成,实现"即插即用"式的励磁系统应用,有必要在公共信息模型中建立励磁系统的模型.在对励磁系统进行详细分析的基础上,抽象出励磁系统的模型,通过继承和关联的方式将励磁系统模型与CIM中现有的模型相结合,充分利用CIM中已有的信息,完成了基于CIM的励磁系统详细建模.     

Concurrent engineering approach to support CIM reference model-based FMS design

As a Computer Integrated Manufacturing system is a complex, expensive and long-term investment, it is necessary to have a good reference model as a first step to deal with its design and operation. A promising way to assist in CIM design and implementation is the Concurrent Engineering (CE) approach. This paper introduces a reference model (based on the CIM-OSA Architectural Framework) that was developed from a functional point of view. Details are given on how this model can be used for the concurrent design of products and Flexible Manufacturing Systems (FMS).

A new type of machine control system to replace traditional CNC

This paper discusses the rationale behind a new form of machine tool control system which has been developed at the Key Centre for Computer Integrated Manufacture (CIM Centre) in Melbourne Australia. The new control system is based upon standard computer hardware and is intended as a replacement for computer numerical control (CNC), which has severe limitations in the CIM environment. The paper also outlines the new CIM possibilities which are now available as a result of this development.
